Does the feed wheel move? If so adjust it's tension on the wire. If not, check for voltage at the motor. If there is voltage and no rotation, check for continuity of the winding, there should be less than 5000 ohms. If no continuity replace motor. If continuity- oil the shaft with light motor oil and see if it releases.If no voltage is measured at motor connections, the fault is on the speed control board. check the fuse, and if that is okay, check the SCR(s) and replace if faulty.

If the feed wheel mechanism does not move, check for voltage at the motor. If there is none present, you need to look for a failure on the control board, which may be a fuse, or even one of the SCR's. Often an 8 amp 200 volt type.

If you can see the tip of the wire, grab it with a plier, and pull. If it comes out easily, you need to adjust the tension on the feed wheel under the cover a little bit. Do NOT touch that adjustment with power on unless you are wearing good gloves, even then there is still a danger of shock as that is the point the secondary of the transformer ties to. If it does not come out, open the cover,and look at the tension on the feed wheel- if it spins and no feeding, the welding wire may be jammed up or corroded to the liner of the handle. If it is all bunched up and tangled, that in itself may be the problem.

If you are using solid wire, you need to use a shielding gas like Carbon Dioxide or Argon. Otherwise you will not get *********** and the wire will leave random blobs.If you are using flux cored wire, you do not need the shield gas as the core is producing the gas shield. This should remedy it.

you may need a gun liner, if the liner is kinked the wire will not feed, causing a "birdnest" and if the wadded up wire touches the cabinet while the trigger is keyed it will get hot and try to weld wherever it is grounding e.g. the cabinet. try a liner first they are only 20 bucks

no unless its designed for gas

Hello, by pulsates, do you mean that the wire feed is what is pulsating while welding? If so, I have had this as well. I found that by turning down my feed rate, the pulsing stopped and the feed was smooth. I hope this helps. If not, contact me again.

Hi there,

Happens sometimes when you're pushing on a rope.
I'm assuming a new spool has just been mounted.

You will need lineman pliers or some other type of heavy duty grippers

• Release the drive wheels
• Pull it back out from the spool side by manually turning the reel
• Snip the end of the wire if it is at all bent.
• Lay the feed hose out in a fairly straight line
• Re-engage the drive wheels
• Pull the feed trigger until the wire either makes it through or stalls
• If it stalls, release the trigger and use the pliers to work the wire back and forth until the it clears the snag area. Try not to twist or kink the wire
  
• Repeat the procedure until the wire has made it all the way through
  

That's about it

Best regards
Mike

You may have a short in the trigger leads that is pulling the weld current back through the leads and through the control cable. The short could be causing the breaker to blow. Can you open up the gun handle (disconnect it from the power source first) and check your trigger leads for cuts or nicks. Also check the outer jacket of the cable for cuts which may be deep enough to allow the current carrying copper to touch the embeded switch leads.

go to praxair ,air gas s j smith or any welding shop they can get it for you,
